Q.If A Date Palm Pup Isn’t Removed From It’s Mom What Happens To The Mom And The Pup Over Time.
Also, if a date palm produces pups does this mean it’s gender is female. And needs a male tree to produce fruit? Also if the pup remains attached to the tree, will it assume the apposite sex In order to produce fruit?

My research shows date palms used to have male and female flowers on the same tree, but translocation separated the trees into males and females. You do need a male tree to pollinate a female tree. Pups will be the same gender as the parent.
It is safe to leave the pups on the tree for years, that will yield a better pup for transplanting. The more pups a tree has, the slower they grow.
